Shanghai Ouzhou (EIB)-Introduction of Round Belt
Round belt: round belt is a kind of belt drive, its cross-sectional shape is circular, which is different from flat belt drive, V belt drive and synchronous belt drive, so it is called round belt. Round belt is also called polyurethane round belt, round belt can be connected, usually PU material, PU is the abbreviation of Polyurethane, Chinese name is polyurethane polyurethane for short. Orange smooth round belt (PU) 1. working principle and application 1. Working principle: round belt transmission is friction belt transmission. The transmission belt is tightly sleeved on the two pulleys to generate pressure between the belt and the pulley contact surface. When the driving wheel rotates, the friction force generated between the belt and the driving wheel contact surface makes the belt move. At the same time, the belt relies on the friction force between the contact surface with the driven wheel to drive the driven wheel to rotate, So as to transmit motion and power. 2. Round belt application: Round belt is used in round belt transmission. Round belt transmission relies on the compression of the belt and the wheel groove to generate friction. It has good elasticity. It can relieve impact and vibration during operation, with stable movement, low noise and excessive load. When the belt slips, it protects the machinery. Round belt drive used in low-speed small power transmission, such as sewing machines, tape disc transmission and other small power or manual machinery as a drive. Shanghai Ouzhou (EIB)-Round Belt regular Customized Table 2. Working Features and Advantages: 1. Because the round belt is elastic body, it can alleviate the load impact and move smoothly without noise. 2. Overload will cause the belt to slip on the pulley, thus preventing damage to other parts. 3, manufacturing and installation accuracy is not as strict as meshing transmission. 4. The belt length can be increased to adapt to the working conditions with large center distance. Disadvantages: 1. The elastic sliding of the belt and the pulley makes the transmission ratio inaccurate, the efficiency is low, and the life is short. 2. When transmitting the same large circumferential force, the outer dimension and the pressure on the shaft are larger than the meshing transmission. 3, not suitable for high temperature, flammable and other occasions. Green rough and orange smooth round belts (PU) 3. round belt types Round belts are generally divided into smooth round belts and rough round belts: round light belts are orange with a hardness of 90, and round rough belts are dark green with a hardness of 85. The surface finish of the light belt is good, the color is bright, the surface of the rough belt is rough, the particles are uniform and neat, the hand feels comfortable, and the application range is wide. According to the material is divided into: pu round belt, tpu round belt and volta round belt. Its specifications can be produced from Φ2~Φ30. Applicable operation mode: packaging machine, printing machine, textile machine, transmission wheel, ceramic tile, cement tile, floor tile, food, wooden products, canned food, newspaper, printed matter, etc.
